This is a sensory tract called the sensory trigeminal pathway. In order for you to sense the pain, the signal must travel from your face through three landmarks to reach the sensory cortex of your brain. First, the receptors in your skin sense pain and send this signal into the trigeminal ganglion.
From here, the pain signal travels through the trigeminal nucleus caudalis in the brainstem. The signal continues up to the thalamus, which projects this signal to the sensory cortex of your brain and you feel pain. This surgery targets the dorsal root entry zone DREZ of the trigeminal nucleus caudalis in the brainstem. When this pain pathway is blocked with the DREZ procedure, the pain signal cannot reach the brain and decreases the processing of pain.
